I do have a couple of sockets wired so each outlet of the double outlet
are connected to each side of a 240 volt line. The reason is it is next
to a 240 volt socket that feeds that 120 volt one. I did that for my
ham radio station so I can run an amplifier on 240 volts. I also have a
120 volt amplifier that draws lots of current so when using it, I have
heaver wire. That is one place where your system of everything on a 240
volt line would have been handy.

That (Edison circuit) isn't cricket. You can't guarantee the neutral
current is within spec. I have 220V outlets wired with normal 12/2
(with white wire painted red) but a shared neutral between two 120V
circuits on opposite legs of the 240V isn't legit.

Dmned right it is. It's not only legal, it was REQUIRED BY CODE

Why are you so obsessed with code?

for kitchen countertop outlets in Canada for over 20 years. The last code
revision is now requiring 20 amp countertop outlets instead of the
"split" 15s.
No reason I see that isn't just as sound as any other Edison circuit,
as long as the breaker is sized for the conductors. If he has 12 gauge
wiring, with a 20 amp double breaker, the neutral current will not
exceed 20 amps.

and if there is 20 amps on each side, there is NO neutral current.

Unless you have inductive and capacitive loads....

Or, worse, harmonics.
